+## Core Components
 
+### Controller
 
-Controller
-----------
+The controller contains CRUD APIs for functions, triggers, environments,
+Kubernetes event watches, etc. This is the component that the client talks to.
 
-The controller contains CRUD APIs for functions, http triggers,
-environments, Kubernetes event watches.  This is the component that
-the client talks to.
+All fission resources are stored in kubernetes CRDs. It needs to be able to
+talk to kubernetes API service.
 
-This is the only stateful component.  It needs to be configured with a
-URL to an etcd cluster and a path to a persistent volume.  The volume
-is used to store the functions' source code.  Etcd is used as the DB.
+### Executor
 
-[Work to extend to other storage backends is planned, see issue #83.]
+The executor has two simple APIs; the router calls both these endpoints.
 
-Pool Manager 
-------------
+* GetFunctionService takes function metadata and dispatches the corresponding executor 
+ type to get the address of a service/pod and returns it to the router.
+ 
+* TapService lets executor know a service/pod is being used; if it's not
+ called for a few minutes the pod(s) backing the service are killed.
 
-Poolmgr manages pools of generic containers and function containers.
+It now supports two different executor types:
 
-It has a simple API; both these endpoints are called by the router.

+* NewDeploy
 
-* GetFunctionService takes function metadata and returns the address
-  of a service.
-  
-* TapService lets poolmgr know a service is being used; if it's not
-  called for a few minutes the pod(s) backing the service are killed.
+These two executor types have different strategies to launch, specialize, and manage pod(s).
+You should choose one of the executor types wisely based on the scenario.
 
-Poolmgr watches the controller API and eagerly creates generic pools
-for environments.  It uses Kubernetes deployments to do that.  The
-environment container runs in a pod with the 'fetcher' container.
-Fetcher is a very simple utility that downloads a URL sent to it and
-saves it at a configured location.
+#### PoolManager 
 
-GetFunctionService "specializes" a pod.  The implementation chooses a
-pod from the pool, relabels it to "orphan" the pod from the
-deployment, invokes fetcher to copy the function into the pod, and
-hits the the specialize endpoint on the environment container.  This
-causes the function to be loaded.  The pod is now specific to that
-function.
+PoolManager manages pools of generic containers and function containers.
 
-This function pod is cached; it's cleaned up if it's unused for a few
-minutes.
+PoolManager watches the environment CRD changes and eagerly creates generic pools
+for environments. It uses Kubernetes deployments to do that. The 
+environment container runs in a pod with the 'fetcher' container. 
+Fetcher is a straightforward utility that downloads a URL sent to it 
+and saves it at a configured location (shared volume).
 
-Router
-------
+The implementation chooses a generic pod from the pool, relabels it to
+"orphan". The pod from the deployment invokes fetcher to copy the function 
+into the pod and hits the specialize endpoint on the environment container. 
+This causes the function to be loaded. The pod is now specific to that 
+function. This function pod is cached; it's cleaned up if it's unused for a few minutes.
 
-The router forwards HTTP requests to function pods.  If there's no
-running service for a function, it requests one from poolmgr, while
-holding on to the request; when the function's service is ready it
-forwards the request.
+PoolManager selects a generic pod from the warm pool, specializes it, 
+and recycles the pod if there are no further requests to the function after a few minutes.
+It makes PoolManager suitable for functions that are short-living
+and requires a short cold start time [1].
 
-The router is stateless and can be scaled up if needed, according to
+However, PoolManager only selects one pod per function, which is not
+suitable for serving massive traffic. In such cases, you should consider
+using NewDeploy as executor type of function.
+
+[1] The cold start time depends on the package size of the function. If it's
+a snippet of code, the cold start time usually is less then 100ms.
+
+#### NewDeploy 
+
+NewDeploy creates deployment, service, and HPA for functions in order to handle 
+massive traffic.
+
+NewDeploy watches the function CRD changes and creates a Kubernetes deployment, 
+service, and HPA for a function. NewDeploy will scale the replicas of a function 
+deployment to the minimum feasible scale setting, if the minimum scale setting of 
+a function is greater than 0. The 'fetcher' inside the pod uses a URL in the 
+JSON payload, which is attached as a parameter to start fetcher, to download the 
+function package instead of waiting for calls from NewDeploy. 
+
+When a function experiences a traffic spike, the service helps to distribute the requests to 
+pods belonging to the function for better workload distribution and lower latency. Also, 
+the HPA scales the replicas of the deployment based on the conditions set by the user.
+ 
+This approach though increases the cold time of a function, but also makes NewDeploy 
+suitable for functions designed to serve massive traffic.
+
+### Environment Container
+
+Environment containers run user-defined functions and are language-specific. 
+Each environment container must contain an HTTP server and a loader for functions.
+
+The pool manager deploys the environment container into a pod with fetcher 
+(fetcher is a simple utility that can fetch an HTTP URL to a file at a 
+configured location). This pod forms a "generic pod" because it can
+be loaded with any function in that coding language.
+
+When the pool manager needs to create a service for a function, it calls
+fetcher to fetch the function. Fetcher downloads the function into a
+volume shared between fetcher and this environment container. Poolmgr
+then requests the container to load the function.
+
+### Router
+
+The router forwards HTTP requests to function pods. If there's no
+running service for a function, it requests one from executor, while
+holding on to the request; the router will forward the request to 
+the pod once the function service is ready.
+
+The router is the only stateless component and can be scaled up if needed, according to
 load.
 
-Kubewatcher
------------
+### Builder Manager
+
+The builder manager watches the package & environments CRD changes and manages 
+the builds of function source code. Once an environment that contains a builder 
+image is created, the builder manager will then creates the Kubernetes service 
+and deployment under the fission-builder namespace to start the environment 
+builder. And once a package that contains a source archive is created, the 
+builder manager talks to the environment builder to build the function's source 
+archive into a deploy archive for function deployment.
+
+After the build, the builder manager asks Builder to upload the deploy archive to the 
+Storage Service once the build succeeded, and updates the package status attached with build logs.
+
+### Storage Service
+
+The storage service is the home for all archives of packages with sizes larger than 256KB.
+The Builder pulls the source archive from the storage service and uploads deploy archive to it.
+The fetcher inside the function pod also pulls the deploy archive for function specialization.
+
+## Optional Components
+
+### Logger
+
+Logger is deployed as DaemonSet to help to forward function logs to a centralized 
+database service for log persistence. Currently, only InfluxDB is supported to store logs.
+
+Following is a diagram describe how log service works:
+1. Logger watches pod changes and creates a symlink to the container log if the pod runs on the same node.
+2. Fluentd reads logs from symlink and pipes them to InfluxDB
+3. `fission function logs ...` retrieve event logs from InfluxDB with optional log filter
+4. Logger removes the symlink if the pod no longer exists.
+
+### Kubewatcher
 
 Kubewatcher watches the Kubernetes API and invokes functions
 associated with watches, sending the watch event to the function.
 
-The controller keeps track of user's requested watches and associated
-functions.  Kubewatcher watches the API based on these requests; when

-message bus between Kubewatcher and the function.  Work for this is

-Message Queue Trigger

 A message queue trigger binds a message queue topic to a function:

+Events from that topic cause the function to be invoked with the

+You can learn more about Fission and get started from [Fission Docs](https://docs.fission.io/docs).
+* See the [installation guide](https://docs.fission.io/docs/installation/) for installing and running Fission.
+* See the [troubleshooting guide](https://docs.fission.io/docs/trouble-shooting/) for debugging your functions and Fission installation.
 
-You can also extend environments or create entirely new
-ones if you want.  (An environment is essentially just a container
-with a webserver and dynamic loader.)
-
-A _trigger_ is something that maps an event to a function; Fission
-as of today supports [HTTP request](https://docs.fission.io/usage/trigger/#create-a-http-trigger), [timed](https://docs.fission.io/usage/trigger/#create-a-time-trigger), and [message queue](https://docs.fission.io/usage/trigger/#create-a-message-queue-trigger) triggers.

+# Fission: Tensorflow Serving Environment
+
+This is the Tensorflow Serving environment for Fission.
+
+It's a Docker image containing a Go runtime, along with a tensorflow serving service.
+
+## How it works
+
+Tensorflow Serving is an serving service that supports both RESTful API and gRPC endpoints. In current implementation,
+Go server launches `tensorflow_model_server` to load in model during specialization. As long as the Go server receives
+requests from router it creates a reverse proxy that connects to RESTful API endpoint exposed by tensorflow_model_server
+and get response from the upstream server for user.
+
+## Build this image
+
+```
+docker build -t USER/tensorflow-serving . && docker push USER/tensorflow-serving
+```
+
+## Using the image in fission
+
+You can add this customized image to fission with "fission env create":
+
+```
+fission env create --name tensorflow --image USER/tensorflow-serving --version 2
+```
+
+After this, fission functions that have the env parameter set to the
+same environment name as this command will use this environment.

-# Go example projects
-
-This repository contains a collection of Go programs and libraries that
-demonstrate the language, standard libraries, and tools.
-
-## The examples
-
-### [hello](hello/) ([godoc](//godoc.org/github.com/golang/example/hello)) and [stringutil](stringutil/) ([godoc](//godoc.org/github.com/golang/example/stringutil))
-
-    go get github.com/golang/example/hello
-
-A trivial "Hello, world" program that uses a stringutil package.
-
-Command [hello](hello/) covers:
-
-* The basic form of an executable command
-* Importing packages (from the standard library and the local repository)
-* Printing strings ([fmt](//golang.org/pkg/fmt/))
-
-Library [stringutil](stringutil/) covers:
-
-* The basic form of a library
-* Conversion between string and []rune
-* Table-driven unit tests ([testing](//golang.org/pkg/testing/))
-
-### [outyet](outyet/) ([godoc](//godoc.org/github.com/golang/example/outyet))
-
-    go get github.com/golang/example/outyet
-
-A web server that answers the question: "Is Go 1.x out yet?"
-
-Topics covered:
-
-* Command-line flags ([flag](//golang.org/pkg/flag/))
-* Web servers ([net/http](//golang.org/pkg/net/http/))
-* HTML Templates ([html/template](//golang.org/pkg/html/template/))
-* Logging ([log](//golang.org/pkg/log/))
-* Long-running background processes
-* Synchronizing data access between goroutines ([sync](//golang.org/pkg/sync/))
-* Exporting server state for monitoring ([expvar](//golang.org/pkg/expvar/))
-* Unit and integration tests ([testing](//golang.org/pkg/testing/))
-* Dependency injection
-* Time ([time](//golang.org/pkg/time/))
-
-### [appengine-hello](appengine-hello/) ([godoc](//godoc.org/github.com/golang/example/appengine-hello))
-
-	goapp get github.com/golang/example/appengine-hello
-
-A trivial "Hello, world" App Engine application intended to be used as the
-starting point for your own code.
-
-_Note_: The `goapp` tool is part of the [Google App Engine SDK for Go](https://cloud.google.com/appengine/downloads#Google_App_Engine_SDK_for_Go).
-
-### [gotypes](gotypes/) ([godoc](//godoc.org/github.com/golang/example/gotypes))
-
-The `go/types` package is a type-checker for Go programs. It is one of the most
-complex packages in Go's standard library, so we have provided this tutorial to
-help you find your bearings. It comes with several example programs that you
-can obtain using `go get` and play with as you learn to build tools that analyze
-or manipulate Go programs.
-
-### [template](template/) ([godoc](//godoc.org/github.com/golang/example/template))
-
-A trivial web server that demonstrates the use of the
-[`template` package](https://golang.org/pkg/text/template/)'s `block` feature.

-This code is a starting point for your Google App Engine application in
-Go.
-
-To run the application locally you need the install the [Go Cloud
-SDK](https://cloud.google.com/appengine/docs/go/#Go_tools) and execute the next
-command from the directory containing this file:
-
-    $ goapp serve app.yaml
-
-To deploy the application you have to first create an App Engine project
-and use it as the application file in all the yaml files.
